Quantum noise spectroscopy of dynamical critical phenomena

Francisco Machado, Eugene A. Demler, Norman Y. Yao +1

The transition between distinct phases of matter is characterized by the nature of fluctuations near the critical point. We demonstrate that noise spectroscopy can not only diagnos…

Mixedness timescale in non-Hermitian quantum systems

Diego Paiva Pires, Tommaso Macrì

We discuss the short-time perturbative expansion of the linear entropy for finite-dimensional quantum systems whose dynamics can be effectively described by a non-Hermitian Hamilto…

Cavity Induced Collective Behavior in the Polaritonic Ground State

V. Rokaj, S. I. Mistakidis, H. R. Sadeghpour

Cavity quantum electrodynamics provides an ideal platform to engineer and control light-matter interactions with polariton quasiparticles. In this work, we investigate collective p…

Probing finite-temperature observables in quantum simulators of spin systems with short-time dynamics

Alexander Schuckert, Annabelle Bohrdt, Eleanor Crane +1

Preparing finite temperature states in quantum simulators of spin systems, such as trapped ions or Rydberg atoms in optical tweezers, is challenging due to their almost perfect iso…

Experimental observation of thermalization with noncommuting charges

Florian Kranzl, Aleksander Lasek, Manoj K. Joshi +4

Quantum simulators have recently enabled experimental observations of quantum many-body systems' internal thermalization. Often, the global energy and particle number are conserved…
